This research investigates the synergistic effects of aluminum oxide (Al2O3) nanoparticles and glass fibers on the mechanical and durability properties of self-compacting concrete (SCC) using an experimental and analytical approach.The experimental analysis involved assessing fresh concrete properties and mechanical performance through tests such as compressive strength, splitting tensile strength, slump flow, L-box, V-funnel, T50, ultrasonic pulse velocity, and bond strength.Durability was evaluated using water absorption, water penetration depth, and electrical resistance tests.

Glass fibers were added at volumes of 0 %, 0.5 %, 1.0 read more %, and 1.

5 %, while Al2O3 nanoparticles were incorporated at weight percentages of 0 %, 0.5 %, 1.0 %, 1.

5 %, 2.0 %, and 3.0 %.

The optimal mix, comprising 2.0 % Al2O3 nanoparticles and 1.5 % glass fibers, resulted in a 61 % increase in compressive strength and a 107.

6 % increase in tensile strength.Water absorption was reduced by up to 46 %, while electrical resistance increased by 265 %, demonstrating improved durability.The combination also enhanced bond strength by 39 %, providing better adhesion between rebars and concrete.

Analytical correlations between mechanical and bond properties were established.This study offers crucial insights for stuart products emcelle tocopherol optimizing SCC performance, making it highly relevant for structural applications.
